Gary notes that Google Analytics is having to temporarily close new registrations due to heavy demand.

Interesting point that it's a good marketing ploy to "close" something due to "heavy demand," but I can tell you when I tried to access Urchin lately it was deadly slow, and this was for a client who was an earlier paying customer! Part of paying for a service (even if you'll no longer be asked to pay), I assume, is a promise that the service will be available and not swamped by "free" users. I have no trouble believing that Google really needs to take a breath here before they let everyone on the planet sign up. Even for Google, that's a lot of data to process, and a lot of logins at once.
